Oh, I should have mentioned yesterday - Gran replied with "
Sure, you can"
, when I wanted to sort out the finances for the uber-rare, rather pricey CastleVania for the old NES and also the PS1 version of Mega Man X4 (the guy who sold them to me even subsequently Friended me on Facebook!). So I had to explain to her, about her inadvertently making a classic Street Fighter joke - i.e. because of Ryu and Ken's Shoryuken attack. She loved it!
I had already bought another game, the Genesis port of Chiki Chiki Boys (that was one of the few Capcom games I was still looking for)... but good old Gran, for giving me the go-ahead and making such a beloved Street Fighter joke 0:-)
